Genes affected
NACC2 (HGNC:23846): (NACC family member 2) Enables several functions, including DNA-binding transcription repressor activity, RNA polymerase II-specific; histone deacetylase binding activity; and protein homodimerization activity. Involved in several processes, including negative regulation of G1/S transition of mitotic cell cycle by negative regulation of transcription from RNA polymerase II promoter; positive regulation of intrinsic apoptotic signaling pathway in response to DNA damage; and protein homooligomerization. Located in chromatin; mitochondrion; and nucleolus. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 02, 2021The c.1519G>A (p.V507M) alteration is located in exon 6 (coding exon 5) of the NACC2 gene. This alteration results from a G to A substitution at nucleotide position 1519, causing the valine (V) at amino acid position 507 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
